Answer:
There are 180 students at the school
Step-by-step explanation:
If 10% of the students like the color purple, then 100-10 = 90% do not like the color purple.
Students * percentage that do not like = students that do not like
students * 90% = 162
Change to decimal form
students *.90 = 162
Divide each side by .90
students *.90/.90 = 162/.90
students = 180
There are 180 students at the school
What do you have to do in that problem?
3.124
3 + 0.100+ 0.020 + 0.004
54+9= 63 m = distance and time=35 sec hence, speed= 63/35=9/5=1.8 m/s
time taken to reach water surface= distance/speed=54/1.8=30 sec
